Gestation is a word describing the pregnancy for animals, and you can use 'gestation period' to describe how long a pregnancy generally takes for a species. I'd like to know if there's a corollary word for the time an animal stays with its parents before leaving.
For example, after birds are hatched, they stay in the nest for a while, but they eventually leave the nest. Is there a single word or phrase that is used to describe the time between hatching and leaving the nest? I imagine different bird species have different periods, and other animals (that don't stay within families their whole life) can also be describe in a similar matter. Perhaps 'puberty', though I'm guessing there's a more specific word.
